An emission ray has a frequency of 5.10 × 10¹Ê Hz. Given that the speed of light is 2.998 × 10§ m/s, what is the wavelength of the ray?

Question

rushwr · Answer

Hey @ataraiders  Use this equation 
$$C = f \lambda $$
Where C is Speed of light,
f= frequency 
$$\lambda = wavelength $$

SO substitute the values and subject wavelength to get the answer ! :)

Did u get it ?

anonymous · Answer

its 15.2898 right

rushwr · Answer

Can u please show me the values again cuz i find it hard to calculate it with the numbers u have given in the question !

rushwr · Answer

powers of tens are not clear

anonymous · Answer

the first one is 10 to the 14th and the other is 10 to the 8th

rushwr · Answer

$$C= f \lambda $$
$$\lambda = \frac{ C }{ f } = \frac{ 2.998 * 10^{8} }{ 5.1 * 10^{14} }= 5.878 * 10^{-7}$$

I hope my values are correct
